The History of the Church is a vital part of the Orthodox Christian faith. Orthodox Christians are defined significantly by their continuity with all those who have gone before, those who first received and preached the truth of Jesus Christ to the world, those who helped to formulate the expression and worship of our faith, and those who continue to move forward in the unchanging yet ever-dynamic Holy Tradition of the Orthodox Church.

1182 Maronites, who assisted the Crusaders during the Crusades, reaffirm their affiliation with Rome in 1182; dedication of Monreale Cathedral in Sicily, containing the largest cycle of Byzantine mosaics extant in Italy.

1228 Sixth Crusade results in 10-year treaty starting in 1229 between Holy Roman Emperor Frederick II and Egyptian sultan; Jerusalem ceded to Franks, along with a narrow corridor to the coast, as well as Nazareth, Sidon, Jaffa and Bethlehem.

1281 Pope Martin IV authorizes a Crusade against the newly re-established Byzantine Empire in Constantinople, excommunicating Emperor Michael VIII Palaiologos and the Greeks and renouncing the union of 1274; French and Venetian expeditions set out toward Constantinople but are forced to turn back in the following year.

1285 Council of Constantinople (Second Synod of Blachernae) discussed and rejected the pro-western interpretation of the Trinity as enunciated by Patr. John XI Bekkos, as well as rejecting the decisions of the Council of Lyons of 1274, and condemning the the Roman (Byzantine) "latinophrones".

Notes

Some of these dates are necessarily a bit vague, as records for some periods are particularly difficult to piece together accurately.

The division of Church History into separate eras as done here will always be to some extent arbitrary, though it was attempted to group periods according to major watershed events.

This timeline is necessarily biased toward the history of the Orthodox Church, though a number of non-Orthodox or purely political events are mentioned for their importance in history related to Orthodoxy or for reference.
